Question

is there any way, how to create and use database from SD card in my app instead of /data/data/com.myapp/databases directory? I know is it unsecure, but are there any special restriction like “database on SD card cannot be bigger then 2GB”?

Thanks

Answer 1

he is a proposed solution which i found in stackoverflow

File dbfile = new File("/sdcard/android/com.myapp/databases/mydatabase.db" ); 
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbfile, null);
System.out.println("Its open? "  + db.isOpen());

here is the link.

UPDATE

i am not sure you can use this along with SQLiteOpenHelper, but you sure can query the database object.

db.getVersion();
db.execSQL(sql);
db.beginTransaction();
db.endTransaction();
db.setTransactionSuccessful();
db.query(table, columns, selection, selectionArgs, groupBy, having, orderBy);

you can do all the things which you expect with a database. SQLiteOpenHelper in only a wrapper class which helps you the extra which we always can do on our own.

EDIT
as for your file size limit i found this link. Is there a file size limit on Android Honeycomb?
